DUMP- CAR.

Specification of Letters Patent.

Patented. Mar. 11, 1913.

Application filed January 1, 1911. Serial No. 603,332."

To all whom it may concern:

Be it known that I, THoMAs R. Mo- KNIcH'r, a citizen of the UnitedStates, residing at Aurora, in the county of Ixane and State ofIllinois, have invented.certa1n new and useful Improvements in Dump-Cars, of which the following is a spec1fication, reference being had tothe accompanying drawings.

My invention relates to dump cars and particularly to cars in which thebed 1s mounted to rock laterally to dump the load at' either side of thecar and is provided with side-gates arranged to be moved or held up outof the way so as to permit the load .to be dumped.

My present invention relates more especially to the construction of theside-gates, and has for its object to provide a side-gate of improvedconstruction which will make it practicable to use such gates on cars oflarge capacity. In dump cars of this type .as at present constructed thebed is comparatively shallow, and. in order to secure a bed vof largecapacity it is necessary to make the bed of considerable length, and asit is objectionable to employ trusses or braces which project laterallybeyond the sides of the'car ithas been a serious problem to constructside-gates of great length without using laterally-projecting braces ortrusses and still secure the necessary rigidity. When it is consideredthat such sidegates may be from twenty-five to thirty feet or more longand only about two feet high the difficulties in the way of properly beappreciated.

I accomplish the object of my invention as illustrated in the drawingsand as hereinafter described.

What I regard as new is set forth in the claims.

In the accompanying drawings,Figure 1 is an end view of a common type ofdumpcar, showing my improved side-gate in end elevation; Fig. 2 is aplan view of about one-half of the side-gate; Fig. 8 is a side elevationof about one-half of the gate. showing the outer side thereof and Fig.41 is an end view.

Referring to the drawings,5 indicates the body of the car, whichis-pivotally mounted on the truck 6 in any suitable way so as to rocklaterally. r f

.' I 34 indicates 7 indicates side-gates, which, in the con structionshown, are carried by straps 8-9 pivoted'to trunnions 10-l1 at. the endsof the side-gate.

12 indicates straps connected to the straps 8 and to straps 13 forholding the sidegates up when the body is tilted at either side of thecar. side-gates are supported may, however,-be varied, as that forms nopart of my present invention.

14-1516 indicates parallel beams or timbers which extend longitudinallyand form the upper, intermediate and lower portions of the frame of thegate, as shownin Figs. 3 and 4:. 1718 indicate metal plates fitted tothe upperand lower surfaces of the beam 14L, .said plates being ofproper width to cover said surfaces. In like manner the upper and lowersurfaces of the 'beam 15 are provided with plates 19-20, andthe'surfaces of the beam '16 are provided with plates 21-22. The ends ofthe plates 17 to 22 are fixedly secured to end-plates 23, which, asshown in Fig 2, are in the form of angle- The manner in which the plateswhich overlie the ends of the beam 1et151-6 and the plates 17 to 22 andthe sides thereof adjacent to the ends. The parts are all boltedtogether firmly so as to be secure. I also provide bearing plates 24 onthe inner faces of the gate near the ends, as shown in Fig. 2. Thetrunnions 10-11 project through the angle-plates 23 and are fixedlysecured to the upper and lower beams 1s-16 by bolts 25-26, respectively,

and are further secured by rivets 27-2S,

as shown in Fig. 3.

2930 indicate spacing-blocks which fit respectively between the plates1819 and 20 and 21; as shown in Fig. 2.

31 indicates ,a series of vertical bolts which extend through theseveral beams 14-1516 and their respective plates and also through thespacing-blocks 29 30, and serve tobind the several parts of the gaterigidly together. The spacing-blocks 29-30 are preferably of about halfthe thickness of the gate,'as shown by. dotted lines in Fig. i

2, and for further bracing the several beams Iprovide channeledfiller-blocks 32'33 at suitable intervals, as shown in Fig. 3, saidblocks .being bolted, or otherwise firmly secured-to thespacing-blocks29-30.

,vertical bolts, which pass is nevertheless thoroughly braced andsupported from end to end without the use of trusses or bracingmeans-projecting out beyond the gate so as to interfere with the use ofthe car in narrow places.

That which I claim as my invention, and desire to secure by LettersPatent, is,

1. A side-gate for dump-cars, comprising a plurality oflongitudinally-extending beams spaced apart, spacing-blocks fittedbetween said beams, end-plates securing the several beams together,vertical bolts con necting the several beams and spacingblocks, andtrunnions projecting beyond the end-plates.

2. A side-gate for dump-cars, comprising a plurality oflongitudinally-extending beams spaced apart, plates secured to the upperand lower faces of said beams, spacing-blocks fitted bet-ween saidbeams, endplates securing the several beams together, and vertical boltsconnecting the several beams and spacii'ig-blocks.

3. A side-gate for dump-cars, comprising a plurality oflongitudinally-extending beams spaced apart, spacing-blocks fittedbetween said beams, end-plates securing the several beams together,vertical bolts connecting the several bean'is and spacingblocks, andchanneled filler-blocks fitted be tween the several beams and connectedto the spacing-blocks, said bolts being fitted in the channels of saidtiller-blocks. I

4. A side gate for dumpwars, comprising a plurality oflongitudinally-extending beams spaced apart, spacing-blocks tit-tedbetween said beams, anglcpla.tes connecting the end portions of saidbeams, vertical bolts connecting the several beams and spacing-blocks,and trunnions projecting be ond said angle-plates.

A side door for dump cars comprising a series of wooden beam-liltebarsassen'ibled one upon the other in a pile, a thin metal reinforcing plateinterposed between the said bar and its adjacent bar or bars amtextending from side face to side face of the door, and means clampingthe whole into a solid structure.

(3. Av reinforced side door for dump cars comprising a plurality ofwooden bars assembled in a pile alternating with plates of steel, eachsaid plate being arranged between the adjacent faces of the wooden barsand extendingsubstantially from face to face of said door, and boltspassing through bars and plates and binding them all into a solidstructure.

7. A side board for dump cars comprising a series of wooden barsextending longitudinally of said board in combination with an alternateseries of steel plates of equal horizontal dimensions, arrangedco-extensive with said bars, and means clamping said bars and platesinto a solid structure.

8. A laminated side door for dump cars comprising alternate layers ofwooden and metal bars arranged in a vertical pile one upon another, eachsaid plate extending from face to face of said door, and bolts passingthrough said doors binding them all into a rigid structure.

9. In a laminated side door for dump cars the combination of a series ofwooden bars extending the length of said door with a series of metalplates of equal width and length with said bars arranged therebetween,and means for clamping said bars and plates into a solid unitarystructure.
